• Minimum localized cavity depth (dimension from the sheathing or the face of exterior insulation
to rear of cladding) – 1/2” (13mm)

• Minimum ventilation at top and bottom of rainscreen cladding system ( 2.4in2/lft minimum)

• Appropriate weather resistive barrier*

• Emphasis on flashing and redirection of water
• Appropriate dead and live load structural design

Continuous Weather Resistive Barriers

Drained & back ventilated systems (D&BV) typically require a continuous weather resistive barrier at
the rear of the cavity, usually located on the outer face of the inner leaf. Typical characteristics are:
• UV stable
• Self-sealing or self-cinching
• Black in color
The UV stability requirement is due to the open joint design of the D&BV system and the potential
long-term exposure of the weather barrier to ultraviolet rays from the sun. The black in color
requirement is to minimize the visual impact of the weather barrier and increase the aesthetic
sensibility. If necessary, both of these requirements can be achieved through the installation of
a black flashing membrane over the existing weather barrier. The weather barrier should be
installed and all penetrations and seams should be sealed per the manufacturer’s written instruction.

• Produced in laminate presses under high pressure, at
high temperature.

• Class A rated per ASTM E84

• ICC ESR #3340

• Abet Laminati, manufacturer of MEG, is a leading
provider of high performance exterior grade wall
panels for rainscreen cladding applications.

• Mounting systems for MEG’s drained and back-ventilated
rainscreen system can be applied with concealed or
exposed application methods depending on the visual
appearance desired and the requirements of local
building codes. It is the responsibility of the purchaser
to assure the final panel assembly meets the standards
required by the local building code.

• MEG panels are available in approximately 80 different
aesthetic options that include solid colors, woodgrains,
and metallic finishes.
